By the way, the discussion of missing oil appears to have produced
some misgivings regarding tilting the motor past 40deg and negative G. There
are of course restrictions which apply, but they should be worded so that
the direction of the force of gravity is included (probably assumed by the
maker).
The water in the swinging pail is a good example and most of us
understand that but there may be some relatively new to the sport who infer
other warnings. It is possible to perform a number of manoeuvres while
keeping the gravity vector as it is in still life, vertical to the
horizontal axes.
A perfect (if not 'the' perfect) example is to be found in the

drivers and on occasion the public forum...........
